This invention relates broadly to the molding of jars such as may be used as flower pots, ornamentations and other analogous purposes.

A very important object of the present invention is in the provision of means for making jars from concrete without the use of an outer mold, jacket or matrix or any other similar support, other than an inside core for the main body pot of the jar, together with a. supporting member of a suitable shape be used for a pattern of the neck of the completed jar and which in turn is supported on a pallet.

A still further object of the invention is to provide a core having strong adhesive qualities so that a desired thickness of plastic material such as mortar may be applied thereto and uniformly adhere to the core.

Other objects and advantages of the in vention will become apparent from a study of the following description, taken in connection with the accompanying drawings wherein:

Figure 1 is a sectional elevational view of my improved apparatus, the mold being removed and the mortar applied to the core pattern.

Figure 2 is an elevational view showing the mold disposed on the base member, certain parts of the mold being broken away to show the arrangement of the core pattern therein.

Figure 3 is an elevational View of the mold.

Figure 1 is an elevational view of the base and vertical rod rising therefrom.

Figure 5 is a vertical sectional view taken through the assembled pallet and neck former.

Figure 6 is an edge elevational view of one section of the neck former.

Figure 7 is a bottom plan view of the pallet.

Figure 8 is a side elevational view of the template.

Figure 9 is an elevational view of the completed jar.

Referring more in detail to the drawings, it will be seen that 5 designates a base pro- 1931. Serial N0. 537,399.

vided on the top face thereof with a relatively small centrally located disk 6. A rod 7 rises from the base and extends through a centrally located opening provided in the disk 6.

The base 5 is adapted to support thereon a mold member 8 that is preferably formed of metal and is in the shape of a bowl as herein shown, although it is to be understood that the shape of the mold member 8 is to be such as to conform with the intended shape of the body portion of the to be formed.

The mold 8 in the bottom thereof is provided with an aperture 9 that is closed by the disk 6 when the mold is disposed on the base 5. To facilitate handling the mold member 8, the same is provided with suitable handles 10.

A lining of suitable cloth, preferably" cheese cloth 11 is placed within the mold S subsequent to the placing of the mold on the base 5, and an edge portion of the lining member 11 is draped over the upper edge of the mold member 8 as shown in Figure 2.

Subsequent to the positioning of the liner 11 within the mold 8, the mold is then filled to its capacity with a cementitious material, preferably a mixture of hydrated lime and sawdust in equal proportions to thereby form what may be termed a core pattern 12 about which the mortar from which the body of the jar is to be made will be applied in a manner hereinafter made manifest.

The material forming the pattern core 12 is then tamped, after which the edge portion of the lining 11 is turned inwardly and cammed upon the pattern core 12, so that as shown in Figure 1, the pattern core 12 is entirely encased within the lining 11. The lining 11 will now serve to retain the shape of the core pattern 12.

I now place on top of the core pattern 12 while the parts are in the position shown in Figure 2, the assembled neck former and pallet shown in Figure 5.

The neck former referred to comprises two sections one of which is in the nature of a circular shell including a disc-like body or plate 13 having a marginal flange 1e perforated as at 15. The second section of the neck former comprises an annular plate 16 adapted to be disposed cireumjacent the flange 14:, and provided at its inner periphcry with a crimped flange 17 adapted to contact the flange 14 as shown in Figure 5.

\Vhen the sections of the neck former are assembled in the manner just explained, the neck former is then positioned on the upper face of a template 18. The pallet on its upper face is provided with series of threaded bosses 19 with which are threadedly engaged the free end of bolts 20 carried by the plate or disk body 13 of the neck former. The disk like body 13 is provided with a centrally located aperture 21 adapted to line with a similarly located aperture 22 provided in the pallet 18 for accommodating the upper portion of the rod 7.

\Vhen positioning the assembled neck former and pallet on the pattern core 12, the assembly shown in Figure 5 is upset so that the disk body 13 will rest flatly on the top of the core pattern 12.

The next step in the operation is then to invert all the parts above referred to, after which the rod 7 is drawn through the pattern core 12 whereby the disk 5 is removed from the assembly. The mold 8 is then lifted from the core pattern 12, and the pallet 18 is then positioned on a turn table 23 as shown in Figure 1. In this connection, it will be noted that the pallet 18 on the bottom face thereof is provided with radially extending ribs 24 whereby to space the pal-- let from the table 23. Also on said under or bottom face, the pallet 18 is provided witha collar 25 that is cooperable with suitable means on the turntable 23 for locking the pallet 18 on the table against rotative movement relative thereto.

As shown in Figure 1, the mortar 26 or other plastic material from which the jar is to be formed, is then applied to the member 11 encasing the pattern core 12, the material 26 being also applied to the outer periphery of the flange 14 and also to the other periphery of the crimp flange 17.

The mortar or plastic material 26 is then smoothed through the medium of a template 27 that is vertically supported on a suitable bracket 28 supported in any desired manner in operative position to the turntable 23. The template 27 has a working or smoothing edge 29 adapted to contact the material 26 for spreading the same and for giving to the finished jar an outer shape corresponding somewhat to the interior shape of the jar as is apparent.

To provide an exterior bead for the neck of the finished jar, the edge 29 of the template 27 at the lower end of the template merges into a concave edge 30 suitable for blades 31 which serve to facilitate the spreading of the material 26 during the smoothing operation of the template.

To smooth and spread the material 26,

the turn table 23 driven from any suitable source of power, (not shown) is rotated relative to the template 27 and obviously as the turn table 23 rotates, the template 27 through the medium of its edges 29 and 30 will suitably work the material 26 to give to the exterior face of the the de sired shape.

Even though I have herein shown and described the preferred embodiment of the invention, it is to be understood that the same is susceptible of changes, modifications and improvements coming within the scope of the appended claim.

Having thus described my invention, what I claim as new is:

In an apparatus for forming pottery, a base, a container like mold of a configuration desired for the finished article, and adapted to have disposed therein a material having porous property for subsequent use as a pattern core for the finished article, removably resting on said base, a separable disk resting on one face of the base, a vertical rod connected with said disk and adapted to extend through the mold, with the upper portion of the rod projecting beyond the top of said mold, said mold being provided in the bottom thereof with an aperture of a diameter slightly greater than the disk and into which said disk when the mold is placed on said base.

In testimony whereof I aflix my signature.

HAROLD HORINE.
